A study on multi-functional welder remote control system using smart phone

In this study, we are a proposed system that could control a multi-functional welder of the current, voltage of the crater, gas control, the wire feeder`s driven, the constant voltage output control, high frequency control, rated current control and the ARC welding control etc., using the mobile-based smart phone. Approximately 90% of user of proposed system are very useful in multi-function welder in their task responded and rest of 10% of the answers don`t need it. 30% answered in 90% of the multi-function welding machine according to age group using a smart phone utilizing this "very difficult" at investigated. However, the use of smart phones is gradually lower the user`s age group can be seen that effective.
